Hummingbird Nest (chapter 1)

Hummingbird Nest (chapter 1)

August 27, 2015

Along West Channel Pond Loop Trail, 1/10 of a mile north of Rocky River Nature Center is an active ruby-throated hummingbird (Archilochus colubris) nest! The lichen-lined nest is well camouflaged in a maple tree beside the east wing of the loop trail, well over 20 feet from the forest floor.

Can you find the ruby-throated hummingbird nest in the mosaic of blues and greens? The 2-inch wide by 1-inch deep thimble-shaped cup nest is in the direct center.

The male and female were observed hovering about the nest August 1. By August 4, only the female remained. She is now (August 5) stationed on the nest, likely incubating 1-3 eggs. The male has begun a 2,000 mile land-flown migration to Mexico or possibly even Central America. Parental care is entirely and tirelessly carried out by the mother. This is probably a second attempt at a brood this breeding season.

The incubation period will last two weeks. I’ll check back mid-August to observe if her clutch has hatched. The hatchlings will grow in size and strength over three weeks and expectantly fledge (leave the nest) the first week in September. Have you ever seen an immature hummingbird learn to fly? With any luck, I just may capture video of the hard work. Check back for an updated Notes from the Field post in late-September for new footage titled "Hummingbird Nest (chapter 2)".

A female ruby-throated hummingbird sits on her nest, diligently incubating 1-3 eggs. The male sports a ruby red throat in prime breeding plumage. I chose not to step into the woods for a closer photograph for fear that I may agitate the focused mother-to-be.
